UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 336,034, dated February9, 1886.

Application filed Jul) 15, 1885. Serial No. 171,706.

To all whom it may concern.-

Be it known that I, CHARLES HENRY BUT- LIN, surgeon, a subject of theQueen of Great Britain and Ireland, and residing at Gamborne, in thecounty of Cornwall, England, have invented certain Improvements inUmbrellas, (for which I have obtained a patentin Great Britain, datedthe 15th June, 1885, No. 7,273,) of which the following is aspecification.

In Letters Patent of the United States No. 311,809, granted me February3, 1885, is shown an arched carrier extending from side to side of avehicle for the purpose of supporting the umbrella therein shown. Theferrule or slider of the umbrella to which the stretchers are attachedis a divided or com pound one, part of the stretchers being attached toone and part to a second division thereof, in order that the ferrule orslider and the stretchers extending therefrom may be opened laterally topermit the umbrella to be attached to the arched carrier above theferrule or slider, and as near the upper end of the stick as possible,the umbrella being thus supported sufficiently low to afford properprotection to the occupants of the vehicle.

Umbrellas of the necessary size for use as vehicle-tops or shelter aresubject, especially when in motion, to a great strain of resisting airor wind, often sufficient to turn them inside out, which also sometimeshappens to umbrellas of ordinary size carried in the hand against abreeze or high wind.

The object of my invention in this present instance, therefore, is todiminish to a mini-v mum the danger of such an accident, in fact,entirely obviating it, unless it bein the presence of very rare andexceptional gales. To accomplish this, I use an auxiliary set of stretchers, extending from the ribs or from the stretchers at their point ofjunction to the ring carrying the inner ends of the ribs, or to anadditional ring fixed upon the stick near to such ring for the ribs.These auxiliary stretchers may be used with each rib and its ordinarystretcher, or with only part thereof, forming braces for the ribs, theregular and auxiliary stretchers forming, when the umbrella is opened, atriangle whose base is the (No model.)

stick and whose apex is the point whereat they support the ribs, givinggreat resistance to any tendency of the umbrella to turn inside outunder stress of wind. This will be better understood by reference to thedrawings, wherein- Figure 1 is a view of the interior of an umbrellaembodying my invention, while Fig. 2 is a view of such an umbrella-framepartially closed, the covering being removed.

In Fig. l the reference-letter G is the stick of an umbrella, of anydesired length, near the upper end of which is secured the ring E, inwhich are pivoted the inner ends of the ribs B. Upon such stick movesthe runner O, in which are pivoted the inner ends of the ordinarystretchers, A, whose outer ends are secured to and pivoted with the ribsB.

D are the additional or auxiliary stretchers, forming braces for theframe when the um brella is opened. At their outer end these auxiliarystretchers D are attached to the ribs B and stretchers A at the point ofunion of the latter. At their inner end they are pivoted in and securedto the ring E of the ribs B, or to a separate ring, F, attached to thestick closely beneath the ring E, so that their fixed inner pivotalpoints are in the immediate neighborhood of the pivotal points of theribs they are intended to brace. Being thus arranged, the movement ofthe runner O in operating the ribs B and ordinary stretchers, A, foreither opening or closing the umbrella also operates upon and places theauxiliary stretchers in proper position, thus obviating any extra careor operation for their use.

lVhen the umbrella is closed, the stretchers A and auxiliary stretchersG lie close to the stick in one plane, each set then forming practicallya continuation of the other, so that the diameter or transverse bulk ofthe umbrella is not materially, if at all, increased, a neat appearanceand compactness being secured thereby. As seen, the stick and the twosets of stretchers form a triangle, G A D, whose base is the stick andwhose sides are the stretchers A D, strain upon the ribs being thusconveyed to the stick at two points of some distance apart, and each ribbeing strengthened and braced at such two points.

This construction is applicable to all sizes and forms of umbrellas, andwith the same advantages, the term umbrella being used to include allsuch forms and sizes irrespective of technical namessuch as sunshades,850.

In Fig. 2, however, I have shown the invention applied to an umbrellahaving the divided ferrule or slide of my patent herein before referredto, in order that the stick of the umbrella may be secured to anumbrella carrier or arch at a point very near to E F, so as to bring theumbrella as closely down as desired to the occupants of a vehicle forsecuring the full protection of the umbrella. The auxiliary stretchersneed not necessarily be applied to each rib in all cases, as in someinstances a few such auxiliary stretchers, or such used
